The charging control system includes a policy and charging rules function (PCRF), a plurality of gateways (P-GWs) each including a policy and charging enforcement function (PCEF), and a relay section including a relay server and a switch that connects the PCRF and the plurality of PCEFs in a hierarchical manner. The PCRF is directly connected to the relay section, whereby the number of sessions is reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charging control method and system in communication network","description":"A charging control method and system are provided that can reduce the processing load on a function of performing charging control.
